Configuring the WSM using Device Manager

VLANs and spanning tree protocol

STP detects and eliminates logical loops in a bridged or switched network. STP forces redundant data paths into a standby (blocked) state. When multiple paths exist, STP configures the network so that a WSM uses only the most efficient path. If that path fails, STP automatically sets up another active path on the network to sustain network operations.

Note: Due to STP's sequence of listening, learning, and forwarding or blocking, lengthy delays may occur. For more information on using STP in cross-redundant topologies, see Web OS Switch Software 10.0 Application Guide, part number 212777-A..

The following table shows the relationship between port, trunk groups, VLANs, and spanning trees. 

Note: By default, all newly created VLANs are members of STG 1.
